A method of operating a food categorization engine includes extracting features from each text description of a training food data set to generate a feature set. The feature set is analyzed to determine sets of food categorization features that correlate to one or more food categories, wherein the sets of food categorization features are defined by a plurality of category vectors. Individual words and/or characters of a text description of a food item received from a user are then analyzed in order to generate a numerical vector representative thereof. The numerical vector is multiplied by a matrix defined by the plurality of category vectors. One or more food categories with which to associate the received food item are automatically selected based at least in part on the multiplication, and the data record associated with the food item is amended to include the selected food categories.
Legal claims defining the scope of protection, as filed with the USPTO.
8. The method of claim 1 wherein the matrix is representative of a semantic feature table and the numerical vector is representative of features of the food item.
10. The computer-readable media of claim 9, wherein the food item categorization engine is further configured to store the numerical vector with a plurality of numerical vectors associated with the individual ones of the one or more food categories in a food data storage arrangement of a fitness management system.
14. The computer-readable media of claim 9 wherein comparison of the numerical vector to a plurality of category vectors comprises, identification of one of the plurality of food categories associated to one of the plurality of category vectors to which the numerical vector matches within a predetermined threshold.
20. The server apparatus of claim 15, wherein the one or more processors are further configured to execute a plurality of instructions of a food categorization engine training application, which when executed causes the server apparatus to: generate the plurality of sets of the plurality of category vectors for each of the plurality of food categories.
